fillers, the operating mechanisms being so Ydesigned and co-ordinated, and the manner of feedingthe illersbeing so arranged that the machine while acting upon a large number of fillers simultaneously occupies a relatively small lfloor space. Y f

In themachine illustrated the fillers are loaded in succession back down in a runway near one endV of the front of the machine vand automatically pushed onto van elevator. The elevator lifts -the `fillers into clamps attached to an endlesschain and are carried thereby with an intermittent movement from station to station across the machine near the top. Means are provided `to prevent the insertion of a filler when the elevator is lifted and Aalso to accurately Ylocate the iillers on the elevator. y, n

At the rst station a filler is pushed onto the elevator and is lifted into the clampand the jaws closed. At vthe second station nothing is done to the filler. At the third station adhesive is applied by a roll that is swung up and rolled across the back of the filler. At the fourth Astation nothing is applied to the filler but it is engagedby a trip that sets in operation the crash feeding mechanism. If there .is no filler at this station crash will not be fed at the neXt station. At the fifth station a length of crash which has been cut oli' from a roll and fed in is lifted and applied to the adhesive coated back of the filler. it the sixth station plates move up and stretch the crash over the back of the filler. p t this station 'the filler trips the mechanism for cutting off and feeding a second strip of crash. At the seventh station the secondvst'rip of crash isappli'ed to the back of the filler. At the 1930. VSerial No. 4725045.

eighth station. ,plates rise and stretch the second strip of crash over ythe back of thek lar. At theeleventh station nothing is done to the filler, but theY filler operates a trip which releases mechanism for cutting off and feeding in a strip of `paper back-lining land head bands. At the twelfth station the back.-

lining and head bands are applied to the back of the filler. At the thirteenth station the back-lining is pressed to place by a rolly which comes up near the middle of the filler and lrolls first one way and then the other.

-t, the fourteenth station rolls rub the backlining about theredges of the back of the filler. At the fifteenth station a roll again rolls over the back-lining. These rubbing rolls turn in tanks containing water so that they apply alittle moisture to the backlining. ,At the Asixteenth station dry rolls run 'along the edges of the back of the filler. i At the seventeenth station a dry roll 'again runs over the back. These wetand dry rolls are elastic,y preferablypneumatic rollsyand they irstengage the filler near the middle of its length androll' one way and then the other way so that they will not slip the back-lining and crash from position. At the eighteenth station nothing is done, the interval being utilized to allow the moisture to dry and the adhesive to set. At the nineteenth station the clamp -is o ened and the iiller with the crash, backining and head bands is discharged to an elevator which lowers the filler onto a delivery chain. The several stations are indicated in Figy of the drawings.

vIElectrical means are arranged for heating the adhesive tanks. There is a motor driven vacuum pump piped to the back-lining applying y means for retaining back-lining w..

strips on their conveyers until they are about to be applied to the fillers.

As the illers are fed in and carried edgewise in a vertical position side by side from stationV to station the distance between stations is very short and the total travel is reduced to a minimum so that while simultaneously operating upon a large number ot iillers regardless of `their size, the machine is very compact and occupies but a relatively small floor space.

The liller conveyer comprises two endless roller chains 1 that extend around sprockets 2 fastened to shafts 3 that are rotatable in i bearing brackets 4 at the ends of the top of Fig. 6. The movable clamp jaws 8 are astened to blocks v9 that have tenons inovably fitting in grooves in the faces of the blocks 6. Springs 10 between the fixed aws and the blocks 9 normally7 torce the movable jaws toward the fixed jaws, Figs. 16-19.

Loose on the shaft 3 at the discharge end ofthe machine isa gear 11, the hub of which is adjustably connected by bolts 12 and lWorm 13 with a toothed disk 14 that is `fastened to the shaft, Figs. 1, 3. kBy this means the `gear 11 may be angularly adjusted with relation to the conveyer sprockets. Engaging the gear 11 is a toothed segment 15 that extends from a collar 16 which is splined on va sleeve 17 that is rotatable on an arbor 18 Which projects from the frame, Fig. 3. The sleeve has .a rocker varm 19 that is connected by a link 20 With a lever 21 Which has a roll 22 that runs in a cam groove in a face of the disk 23 that is fastened to the` cam shaft 24, Figs. l, 3. The collar 16 has a groove engaged by a yoke 25 at the upper end of an angle lever 26 that is connected by a link 27 with a lever 28 which has a roll 29 running in a cam groove in a'face of the disk 3G fastened to the cam shaft, Figs. 1, 3. cams are so timed that the segment 15 is os# cillated to impart a .rotary movement to the gear 11 and then slide sideivise outy of engagement with the gear. and swing back and forth again transversely into engagement With the gear, and thus through the gear impart intermittent movements to the .conveyor and carry the fillers from station to station. To prevent accidental movement of the conveyerand dislocation of the fillers carried by the conveyor, a toothed latch 31 is arranged to engage the teeth of the gear, While the segment 15 is disengaged from the gear 11. This latch is movable in a bracket 32 and has a stud 33 which is engaged by the forked endof an angle lever 34 that is connected by a link 35 With a lever '36 controlled by `a rcam groove in a face of the disk 36, Fig. 1; This cam is timed to cause the latch to engage the gear just bef'ore the segment is slipped out and hold the gear until the segment is again engaged with the gear. The calm shaft has a gear 37 that is connectedbysuitable gears 38 With a driving pulley 39, Fig. 2.

The clamps are normally closed by the springs 10 and they are opened at the loading station for receiving fillers, then closed and again opened at the discharge station for delivering the fillers. Slidable horizontally in Ways in the frame beneaththe conveyer chains at the loading end, are bars 40 that at their outer ends have teeth Which are engaged by toothed segments 41 fastened to shaft 42 that extends across theframe,

Figs, 1, 2, 3. A rocker arm 43 is adjustably connected with the shaft 42 by means of a toothed disk 44, Worm 45 and bolts 46,

Fig. 1. The arm 43 is connected by link 47 with a rocker arm 48 on an arbor 49 that has a rocker arm 50 Which is controlled,

by cam 51 on the cam shaft, Figs. 1, 11.

Pivoted to the inner ends of the bars 40 are latches 52 that, when the bars arepushed The Fig. 1.

530 at the bottom of the bar runways, out of the path 4of the clamps, and that When the lbars are drawn out by the segments ride up the inclines and engage the blocks 9 and pull themovableclamp jaw open, as;y

illustrated in Figs. 16 and 17. The cam 51 is timed so that the latch bars will pull open'a clamp javv just before it reaches a the Worm 45, the distanceofopening of the .clamps may be yregulated for fillers of different thicknesses.

At the discharge end of the machine the sliding rack bars 53 are engaged by toothed segments 54 on a shaft 55 which has a rocker arm 56 that is connected by a link, 57 with a lever 58 which is controlled by a cam on the face of the diskr59 Von the cam shaft, By these means the bars 53 are pushed in at the properV time so thatthe blocks 60 which they carry Will engage With the blocks 9 that carry a movable clamp jaw and open the clamp and release the liller held thereby, Figs. 18, 19. After the filler has been released the bars 53 are ivit-hdrawn and allow the clamp to close.

The mechanisms for loading the fillers and elevating them to the conveyer clamps are shown in Figs. 7-15. The fillers 61 are `placed by hand back down on a fixed horizontal runway 62 between vertical side Walls 63, that are supported by a bracket 64 fastened to the frame of thevniacliine. The Walls L63 are adjustable toivard and from each other for different thicknesses of fillers, being fastened to blocks 65 that may be moved transversely on the bracket by means of right and rleft threaded screws 66, Figs.

Cil

749. On one Wall is a spring latch 67 for positioning the fillers, which are pushed in past the latch and then drawn back against it, Fig. 9. At the inner end of `the runway there is a stop pin v68 normally held raised by springs 69, Fig. 7, to prevent fillers from being pushed in beneath the raised elevator and becoming jammed when the elevator comes down. The fillers are fed from this position onto the elevator 70 by a spring finger 71 carried by an arm 72 that 'projects from a sleeve 73 Which is free to move along but rotates with a shaft 74, Figs. 8, 10, 15.

An arm 75 .Which engages the sleeve 73 is l linger is moved back and forth for feeding the fillers from the runway onto the eley vator.

The shaft 74 has an arm 79 which is connected by a link'80 With a lever 81 that has a roll 82 in a vertical cam groove 83 in a
